Evaluation of Virtual Operating Systems and Switches under Ring, Star and Tree Topologies for Streaming Large Data Sets

This paper discusses architectural performance of virtual operating switches, and systems under various topological structures to handle packet deliveries of large streaming and dynamic data sets. The topology structures studied include: tree, fully connected mesh, and star. A virtual network framework is developed that can generate any number of nodes with re-configurable parameters. An evaluation on memory requirements, disk-space, and CPU usage on three different virtual network switches (openvSwitch, openSwitch, openWRT) were also investigated. Two specific protocols–Routing Information Protocol (RIP) and Open Shortest Path First (OSPF) are tested against bandwidth requirements
